  More than 900 shallow wells have been drilled at Rotorua for space and water heating for private homes, hospitals, schools, motels, hotels, and other commercial and industrial uses. At peak use, around 430 wells were operating. Currently fewer than 300 production and injection wells are operating, for approximately 140 consents takes. About 90 of the wells are less than 200m deep and typically recover geothermal fluid at temperatures of 120 to 200°C.

That is ‘sitting on a hot spring’ if you can go less than 200m down and get 200 c water - that is superheated steam.
